"I chose Caloundra because it has a slight retro feel to the main street, and I see that as being a positive thing," Mr Chapman said.

"For me it's spot on for a backdrop for retro cars and music."

Apart from the Show and Shine on Saturday, the event will include car runs across the Sunshine Coast on the Friday, a Show and Shine precision driving display at Corbould Park on Sunday and a beach breakfast on Monday morning at Kings Beach.
